我正在尝试使用盖茨比图像,但无法读取null的属性'childImageSharp'。我找不到错误在哪里。 Topsection.js是Component下的一个组件。 image.jpg在src / images / images.jpg内部。仍然出现错误,无法解决。我已经附上了所有文件。请帮我解决。
Topsection.js
const TopSection = () => {
const data = useStaticQuery(graphql`
{
featureimg: file(relativePath: { eq: "image.jpg" }) {
childImageSharp {
fluid(maxWidth: 60) {
...GatsbyImageSharpFluid
}
}
}
}
`);
return (
<>
<div className="first-post-thumbnail">
<a href="/best-keyboard-for-wow/">
<Image fluid={data.featureimg.childImageSharp.fluid} />
</a>
</div>
</>
);
};
export default TopSection;
错误:
35 | <div className="first-post-thumbnail">
36 | <a href="/best-keyboard-for-wow/">
37 |
> 38 | <Image fluid={data.featureimg.childImageSharp.fluid} />
| ^ 39 |
40 | </a>
41 | </div>

假设您已正确设置文件系统,并且GraphQL可以使用该图像。
尝试:
import Img from "gatsby-image"
// other imports
const TopSection = () => {
const data = useStaticQuery(graphql`
query {
featureimg: file(relativePath: { eq: "/images/image.jpg" }) {
childImageSharp {
fluid(maxWidth: 60) {
...GatsbyImageSharpFluid
}
}
}
}
`);
return <div className="first-post-thumbnail">
<a href="/best-keyboard-for-wow/">
<Img fluid={data.featureimg.childImageSharp.fluid} />
</a>
</div>;
};
export default TopSection;
文件节点的relativePath
字段相对于您在gatsby-source-filesystem
中指定的目录。
我建议使用<Link>
组件而不是本机<a>
(锚点)进行内部导航:
<Link to="/best-keyboard-for-wow/">
在GraphQL游乐场(localhost:8000/___graphql
)中检查查询,以检查拼写和结果。

Clearing the cache 对我来说是成功的(除了删除 package-lock.json 并重新运行 npm install):
gatsby clean
答案 2 :(得分:0)
清理项目并重新运行“npm install”工作
npm run clean
然后
npm install
